upgrade reqwest to v0.10.0

This will improve build time and binary size as follows:

* Before

- **Compile targets**: 220
- **Build time**: `cargo build --release  1264.95s user 39.72s system 335% cpu 6:29.14 total`
- **Binary size**: 6578568 bytes

* After

- **Compile targets**: 170
- **Build time**: `cargo build --release  1130.64s user 32.15s system 359% cpu 5:23.69 total`
- **Binary size**: 6107088 bytes

* Differences

- **Compile targets**: 1.29x smaller
- **Build time**: 1.23x faster
- **Binary size**: 1.07x smaller
